I own a 2003 Jeep Liberty (KJ) and just after I bought it for no reason it stalled at a stop light.It re-started but wouldn't idle the second I let off the gas it died. So I had to 2 foot it home. After it sat for approx. 30mins It started and ran wonderfully and nothing happened until 5 days ago. I came to a stop sign and it died, once again 2 footing it home. My husband checked it out, nothing registered on teh computer. Of course after it sat for a bit it once again ran wonderfully but this time, it only lasted a day. Anyone else ever have this happen or any ideas as to what the Heck is wrong with it? I am all ears.

Thanks.

I been tring to find a reply for you on this and have contacted a friend that had a similar problem on his grand. Now heres what he wrote:(I hope this helps you)
My Grand Cherokee would die after it was run for a while. It just got steadily worse until it would only run about 5 minutes. As long as I kept the engine revving it would keep running but when I dropped to idle it would quit. Let it set a bit and it would restart OK. It also did not show anything on the computer. Finally I took it to the shop and they hooked it up to their scanner. After a good warm up it quit and the scanner showed a defective crank sensor.

I don't expect the Liberty has exactly the same setup as the Grand Cherokee but I expect it will be something the same in that it likely has a crank sensor. I would suggest you have a shop put a scanner on it and see if it shows anything. If possible try to duplicate the circumstances that makes it quit.

 

I had the same problem with my 04 Libby . Replaced crank sensor and its been great 2 years now.
